Description

Technical Field

[0002] In recent years, hydrogen fuel cell technology has developed rapidly in my country, and has successfully driven the diversified development of a series of upstream and downstream hydrogen energy companies. Each hydrogen energy company has developed its own system engine. At present, the market demand for hydrogen fuel system engines is small. In order to control R&D investment and reduce production costs, each company generally only invests in semi-automatic or manual assembly lines and manual test stations. After the hydrogen fuel system engine is assembled, the whole machine needs to be tested for air tightness. After passing the test, it is transported to the system test bench experimental warehouse for performance testing using a quick-install trolley device. The starting performance, rated operating conditions and idle operating conditions of the test system engine, power, voltage, current, gas consumption rate, temperature, coolant ion concentration, positive and negative poles of the stack, and insulation resistance to the ground must all be tested and qualified before the whole machine is tested. During the entire test process, the movement of the system engine is mainly completed manually, which is labor-intensive and difficult to operate, and it is easy to cause damage to the system engine during transportation.

[0003] For example, the tooling for assembling a hydrogen fuel cell engine system disclosed in CN201920341637.5 realizes lifting and lowering through a connecting rod structure and realizes the overall flipping of the test component, but the support frame structure has poor reliability, which can easily cause the test component to fall and cause damage to the component.
